Understanding Oracle Query Execution Plans

Queries must essentially be optimized for performance for ensuring perfect database performance and optimum throughput. This sort of queries would not adversely impact the overall database performance. The DBA must, first of all, examine the performance bottlenecks that are present in the SQL code. For successfully doing that, a DBA must have the thorough ability to understand and also, effectively interpret an Oracle Query Execution Plan. A DBA is conversant and quite contented with commands like EXPLAIN_PLAN.

Tremendous Knowledge of Performance Metrics

The Oracle system has a variety of key performance indicators or KPIs. These can be used to chart and monitor the performance of the entire database ranging from scalability and reliability to the ability of the DBA himself. This is why they are often brought up in performance reviews, to see how aware a DBA is. Remote DBA experts are not only aware of the various performance metrics but also know how to retrieve the values, tune the database to ensure it is working as expected, and also to devise new metrics if needed.

 

Tuning and Monitoring

Beyond creation and routine administrative duties, the primary role of any DBA is to keep improving the performance of the database. The ability to get the best performance out of a system is what separates real database experts from the novices. There are various factors that affect a system’s throughput, located at various levels of abstraction in the system ranging from the network to the database config or poorly designed queries. The best remote DBAs are not only familiar with these issues but also well aware of how to spot what is wrong by sifting through statistics and logs through a combination of drill-down operations and pure intuition. The next step, of course, is the remedy. Performance tuning is easier said than done but is certainly achievable if your system is in the right hands.

Effective Maintenance with Low Downtime

Scheduled updates and patches are extremely important to keep a database running at top performance. Unfortunately, the installation of the same could be a pretty mundane affair that keeps the database offline for a significant time period. Remote DBAs understand the best times to roll out the updates and also the best practices to ensure that the downtime is minimal and a rollback to the last stable state is possible in case anything goes south. This ensures you will be able to go about your work with minimal hassle and may not even know when the updates are being performed.

You must understand, in this context, that the popular Oracle health monitor actually is a vital tool for examining integrity issues present in the database transactions, structure, core dictionary objects, redo logs, and media. Prompt, proactive, and judicious use of this wonderful tool could go a long way in preventing all database integrity issues and problems before a disaster could take place.  It is the responsibility of a qualified and certified Oracle DBA expert to ensure continued reliability and availability of a database.
